Imaging was performed on a PET/CT scanner (mCT, Siemens Healthineers, Munich, Germany). To ensure an optimal positioning of the patient the procedure was accompanied by a physician and a dosimetrist of the department of radiation oncology. The simultaneously acquired CT imaging consisted of a ...
Performing a CT scan requires a dedicated CT scanner, which acquires a sequence of 2D radiographs from angles all around the object and records the geometrical parameters needed for the mathematical reconstruction algorithm, which computes a 3D image of the object’s interior. To facilitate this ...
For the local cohort, CT images were obtained using a CT scanner (Somatom Definition Flash; Siemens Healthcare, Forchheim, Germany) with the following parameters: detector collimation of 0.625 mm, 120 kVp, 150–200 mA, and a reconstruction interval 1 mm. Image data were reconstructed ...
Each participant underwent a routine brain PET scan 50 min after receiving an intravenous injection of [18F]florbetapir (median [inter-quantile range]: 308.95 [284.90, 341.33 MBq]), using the digital uMI Panorama PET/CT scanner (United Imaging Healthcare). Prior to PET acquisition, a low-dos...

MPICTfollowed by CCTA were performed on a third-generation dual-source CT scanner (SOMATOM Force, Siemens Healthineers). Hyperemia was induced by slow bolus injection of 0.4 mg regadenoson. A 40-ml bolus of iopamidol (Isovue, 370 mg/ml, Bracco, Italy) was injected at 5.5 ml/...
All patients underwent examination on a 64-slice spiral CT scanner (Siemens Somatom Diagnostics Flash, Siemens AG). The scan included four phases: pre-contrast phase (PCP), corticomedullary phase (CMP), nephrographic phase (NP), and excretory phase (EP). Automatic tube current modulation based ...

All PET/CT studies were carried out using a PET/CT scanner (Discovery MI; GE Healthcare, WI). After the whole body PET/CT scan, patients underwent thin-slice CT chest scan while holding their breaths. Data obtained by Discovery MI were transferred to the Advantage Workstation (version AW ...
The Biograph TruePoint 40 scanner—another vendor PET/CT scanner—was excluded from our analysis. This is due to its lower spatial resolution and distinct acquisition and reconstruction parameters, specifically the non-time-of-flight and non-point-spread function. CT images were initially acquired ...
